Microsoft Releases June 2026 Patch Tuesday Update for Windows 11

Microsoft has officially started rolling out the June 2026 Patch Tuesday update for Windows 11. Based on our tests, this update is one of the most feature-packed releases in recent times, offering a blend of hardware optimizations, AI-driven features, performance improvements, accessibility enhancements, and critical security fixes.

The update, designated as KB5094126 (OS build 26200.8655 and 26100.8655), is applicable to Windows 11 versions 25H2 and 24H2. Unlike the recent monthly updates, which provided modest new features, the June release delivers something for almost every type of user—from casual users to IT administrators and developers.

The update follows Microsoft’s standard two-phase rollout process:

• Gradual Rollout: Features are introduced incrementally over time.
• Normal Rollout: Critical security updates are deployed to all eligible devices immediately.

What’s New in the Windows 11 June 2026 Patch Tuesday Update

Here’s a detailed overview of the key features and improvements included in this release:

Low Latency Profile: Enhancing Performance

The highlight of this update is the Low Latency Profile, though Microsoft has not explicitly mentioned it in the release notes. This CPU tuning method speeds up app launches and enhances core shell experiences, such as the Start menu, Search, and Action Center.

How It Works: The Low Latency Profile initiates precise CPU bursts when opening apps or system components, bypassing the typical CPU scheduler delay. This leads to faster response times, particularly noticeable on mid-range and older hardware.

This feature is part of the gradual rollout phase, so users should allow it to activate naturally rather than attempting to enable it manually.

Mandatory Secure Boot Certificate Updates

Windows 11 now includes updated Secure Boot certificates issued in 2023, replacing the older 2011 certificates that expire in June 2026. Secure Boot ensures that only trusted software runs during system startup, serving as a crucial security layer for modern systems.

Most devices have already received these certificates in prior updates. However, older hardware or enterprise-managed devices might encounter issues if certificates are not updated in a timely manner. A new Group Policy setting, LimitSecureBootRequiredServiceData, has also been introduced for enterprises to control Secure Boot telemetry.

Gradual Rollout Features

Several new features are being deployed incrementally:

• Shared Audio: Enables two users to listen to the same audio stream using Bluetooth LE Audio broadcast technology.
• NPU Awareness in Task Manager: Task Manager now includes new columns to monitor Neural Processing Unit (NPU) usage on a per-process basis.
• Multi-App Camera: Allows multiple applications to access a webcam simultaneously.
• Custom User Folder Names: During setup, users can now assign custom names to their user profile folders.
• Magnifier Enhancements: Improved clarity in announcements and support for magnifying protected content enhance accessibility.
• Improved Windows Hello Defaults: Biometric sign-ins now consistently default to facial or fingerprint recognition, unless a PIN is used multiple times consecutively.
• Enhanced Windows Search: Search now prioritizes results for queries as short as two characters.

System and Performance Improvements

The June update also brings several system-level refinements:

• Storage Settings: Users can now specify drive sizes in gigabytes instead of megabytes, simplifying Dev Drive creation.
• USB Improvements: Enhancements to the USB3 and USB4 stacks improve connectivity while reducing power consumption issues.
• Clipboard History Performance: Accessing and navigating clipboard history is now faster and more reliable.
• Font Rendering Updates: The Times New Roman font family has been updated to improve diacritical mark positioning for Greek and Cyrillic scripts.
• Task Scheduler Improvements: Column width adjustments in Task Scheduler now persist across sessions.
• Microsoft Store: App downloads are faster, and error messages are clearer when group policy settings interfere with updates.

Bug Fixes and Known Issues

The June update resolves several significant issues:

• EFI System Partition Errors: Fixes an installation error (0x800f0922) caused by insufficient EFI partition space.
• Desktop Icons: Improves the reliability of loading desktop shortcuts after restarts or updates.

As of this release, Microsoft has reported no known issues with the update, indicating a positive level of stability and quality.

How to Install the June 2026 Patch Tuesday Update

To install the update:

1. Go to Settings > Windows Update > Check for updates.
2. Install the update KB5094126, which will upgrade your system to OS build 26200.8655 or 26100.8655, depending on your Windows 11 version.

Some features may take additional time to appear due to the gradual rollout process. This is normal, so there’s no need for concern if new features are not immediately visible.

Conclusion

The June 2026 Patch Tuesday update is a comprehensive release that improves performance, security, and user experience. Whether you’re a casual user, IT administrator, or developer, this update delivers valuable enhancements and fixes. We recommend installing it as soon as it becomes available on your device.
